The shooting occurred early Tuesday morning at a home in the 400 block of 54th Street.

"It's a young lady who had an altercation with her live-in boyfriend," Sgt. Greg Key told WPBF 25 News.

Police said the woman claims to be a former police officer from Colorado. She told detectives she killed her boyfriend in self-defense.

"We're kind of continuing to gather the evidence and, at some point, we will present it to the state attorney's office," Key said. "And if they find it's sufficient evidence to make an arrest, we will at that time."

Police haven't released the identities of the victim or his girlfriend.
